Question

which of the following statements are true? select all that apply.
an electron has a negative electrical charge.
a proton is the same size as an electron.
all of an atoms electrons are located outside its nucleus.
are fast - moving particles called electrons. each electron has a negative electrical charge. an
electron is much smaller and lighter than a proton or a neutron.

Explanation:

• Electron charge: Electrons have a negative electrical charge. This is a fundamental property of electrons.
• Electron location: In an atom, electrons are located outside the nucleus. The nucleus contains protons (positive charge) and neutrons (neutral charge), while electrons orbit around the nucleus.
• Proton - electron size/mass comparison: Protons are much larger and heavier than electrons. A proton has a mass approximately 1836 times that of an electron. So the statement “A proton is the same size as an electron” is false.

Answer:

An electron has a negative electrical charge. All of an atom’s electrons are located outside its nucleus.
